In this paper we compare three existing methods to measure the Modulation Transfer Function (MTF) of a
printing system. Although all three methods use very distinct approaches, the MTF values computed for two of
these methods strongly agree, lending credibility to these methods. Additionally, we propose an improvement to
one of these two methods, initially proposed by Jang & Allebach. We demonstrate that our proposed modification
improves the measurement precision and simplicity of implementation. Finally we discuss the pros and cons of
the methods depending on the intended usage of the MTF.
